How is NumUVVectors computed ? it should be xdim*ydim.
or (xdim+1)*(ydim+1) if range of #for are (0, ydim) and (0, xdim)

Range problem, b/xdim is never reaching 1.0, same for a/ydim.

I hate that code:

>       #if (a < ydim-1 & b < xdim-1)

because it seems, to my eyes, ambiguous about order of operations.

Please put more ().
